The March 23 editorial “Banning assault weapons,” concerning a bill to do just that in Maryland, was ironic. As an argument for the measure, the editorial cited the 2002 killing spree of John Allen Muhammad and Lee Boyd Malvo because they used a weapon akin to the AR-15 to shoot 13 people in the Washington area. The irony is that there was an assault-weapons ban in place at the time, and it did not stop these individuals from committing their criminal acts.

So much for the effectiveness of assault-weapons bans.
